RAILWAY-CAR VENTILATOR.

Specification of Letters Patent.

Patented March 17, 1908.

Application filed September 30, 1907. Serial No. 395,186.

To all whom it may concern:

e it known that I, HARRY T/VILBUR YOUNG, a citizen of the United siding at Alameda, in the county of Alameda tain new and useful Improvements in Rail- Way-Car Ventilators, of which the following is a specification.

e apparatus constituting the subjectmatter of this invention relates to'means for providing an automatic ventilation of railway cars.

Among the several objects is prin'iarily to provide a mechanism whereby the k train will cause a positive circulation of esh air into and through a car, whereby the atmosphere at the interior of the car will be readily and frequently changed and without attention on draft before mentioned.

For a full understanding of the invention, including its mode of operation and advantages, reference is to be had to the accom panying drawings, in which igure 1 is a vertical longitudinal section of my apparatus shown in connection with a diagrammatic view of a railway car; Fig. 2 is a front end view of the receiving end or funnel; Fig. 3 is a horizontal sectional view of the mechanism illustrated in Fig. 2, and Fig. 4 is a side elevation of the same mechanism, illustrating means whereby the said funnel may be secured to the main conduit or pipe.

In all the figures of the drawings, similar parts are referred to by like reference characters.

Referring specifically to the drawings, the numeral 10 indicates a fragment of a conventional type of railway car, to which my im provement is attached. A pipe or conduit 11 is connected with the car body at any suitable or convenient point and is directed forwardly, being provided at its extreme front end with a flaring hood or funnel 12. It will be understood that the conduit and funnel will be so disposed as to be directed beyond the outlines of the car and. with the i the direction in which the car is to move and with the rear or inner end of the conduit opening into the interior of the car, and that both ends of the car are to be equipped with similar apparatus, although only one end is illustrated. At the extreme outer end of the funnel I provide States, re- 1 f I l I f 1 l a screen 13, designed to deflect any large particles of foreign matter, such as hail, heavy cinders, and the like, and preventing the 1 same from entering the funnel. 1 also pro- I vide just in the rear of the aforesaid screen another screen 14 which may be of finer I mesh than the former, and for the purpose of deflecting other or finer particles of foreign j matter. Between the planes of the screens I and at the bottom of the funnel is provided I an opening or slot 15 through which all par- I ticles of matter which are deflected by the j inner screen may find their way downwardly and outwardly. As indicated the funnel has a flaring form, the flare being lateral direction only so as not to increase the height of the apparatus unnecessarily above the top of the car. It will be understood however that if the funnel should be located upon the side of the car as may be in some desired, the exact form of the instances, if funnel would be varied accordingly.

preferably in a Any suitable means may be provided whereby the funnel may be detachably secured to the main portion of the conduit 11, such means being herein indicated as hooks 16. "he purpose for providing ready removability of the hood is to enable the screens to be renewed or repaired whenever necessary, and also to gain access to the mechanism located in the rear of the hood. A baffle member or deflector 17 is mounted at any convenient place in the conduit 1.1, preferably near the entrance thereof close to the funnel. Said baffle member is of such diameter as to substantially fill the opening of the said conduit and is intended to rotate rapidly therein in a plane transverse to the conduit. The baffle member is journaled in any suitable supports, indicated as by 18 and 18, the axis 19 of the said member being mounted in suitable bearings 20 supported by the supports 18 and 1S. aid bearings may be of any suitable type so as to compensate for the end thrust to which the battle member is necessarily subjected as well as to take up any lateral wear of the axis 19. -Arrangedv just in the rear of the rotary baffle member is a rigid deflector 2.1. This deflector is shown as being substantially crescent shaped and extending across the bottom of the conduit and substantially one-half way up the sides. This member 21 may be constructed as a part of the member 18 if desired. The function of the deflector 21 is to effectively exclude all fine'partic'les of dust,

air coming into ing all superfluous mountings dirt, rain, or the like, which may have passed the screens 13 and 14, the deflector 21 coopthe bafllel'? to drive such particles of foreign matter downwardly through a slot 22, just beneath the baffle and outside the deflector 21. When the train or car is in motion air will enter the funnel and the force of the blast thus created will cause a positive rotation of the baffle member 17, the blades of which. will drive all particles of dust and the like downwardly through said last mentioned slot.

The inner end of the conduit 11 it is to be understood will be positioned at any desirable compartment or portion of the car, depending upon the nature of the car, and the service to be met. At any suitable place in the conduit, preferably at or near the inner end thereof, is to be placed a suitable form of register or damper 23, whereby the blast of the car may be controlled or entirely out off as would be desirable in passing through a tunnel in order to exclude objectionable smoke and gases. At any suitable point in the conduit is connected a branch pipe 24 designed to lead to the smoking room, or any car to which the apparatus is attached. branch pipe 24 will also register or damper 23.

The mechanism constituting the apparatus of this invention will be made of any ma- Said terial suitable for the purpose and the several parts will be supported in place by any means which may suggest themselves to a skilled mechanic or car builder. As above intimated the exact location of the hood relative to the line of the train is immaterial so long as the mouth of the hood is given its necessary exposure to the atmosphere. On modern cars, such as are of a height requiror trimmings to be removed or excluded from the top of the dome or clear-story, it would be desirable to locate the funnel just to one side 0 the dome and on the top of the car. arranging the hood, say at the left corner of the car as viewed from the interior, there would be no possibility of the foul air' discharged by one ventilator from entering the funnel of the ventilator on the next succeeding car.

Having I claim as new thus described the invention, what and desire to secure by Letters Patent of the United States, is 2- 1. The hereindescribed ventilator for rail way cars comprising, in combination, an air conduit, a funnel detachably secured to one end of the conduit, a plurality of screens guarding the mouth of the funnel, the bottom of the funnel being slotted between the planes of the screens, a rotary baffle member to the ournaled in the conduit in proximity other compartment of the,

be provlded with a l l i l l l air into any compartment of the car.

'cludin coarse particles of foreign matter b from the funnel, means for excluding dust,

rain, and the like from the conduit, such latter means comprising a baffle member journaled for rapid rotation in the conduit and in a plane transversely thereof and a stationary deflector adjacent thereto, the bottom of the conduit being slotted just outside of sai deflector, and hand operated means for con trolling the passage of air through the conduit.

3. In combination with a ventilator therefor comprising conduit means to convey air into a plurality of compartments of the car, a baffle member mountec for free rotation in the conduit near its forward end, the conduit being slotted beneath the said baffle, a stationary deflector cooperating with said battle to direct foreign partic es of dust and the like outwardly through said slot, and means ling the passage 0 railway car, a

for control.

4. In combination with a railway car ventilator conduit, baffle and deflector means therefor comprising a rotary baffle member of substantially the diameter of the conduit and a stationary crescent shaped adjacent to and in the rear of the said rotary member, the conduit being slotted below the rotary member, supports for the rotary bafli member, one of said supports constituting an extension of said stationary bearings for the baffle member mounted in said supports.

5. In combination witl a railway car, a ventilator therefor comprising a tubular conduit, a flaring the outer forward end of the conduit, a plurality of screens at the mouth of the funnel and the funnel being slotted at its bottom between said screens, being slotted at its bottom in rear of the funnel, and means 1 HARRY WILBUR YOUNG.
